top posting is superior anyway --- *ducking to avoid thrown objects*
If I recall correctly, when doing something like that with a polycom I
had to set the registration interval absurdly low, like 20 seconds or
something. I think the Polycom didn't send keepalives and that was the
workaround.
top posting so as to not make thread even more confusing.
Nick,
I have nat=force_rport,comedia in sip.conf. It is my understanding that
nat=yes is deprecated?
Thanks,

Make sure you have nat=yes in your sip.conf either under globals or

Hello,
CentOS 6.x and Asterisk 11.x
I have an interesting, to me at least, situation. Using a Polycom
501(also tried with X-Lite). I have set up Asterisk to accept
registration from the Polycom and it registers successfully but then
withing 30 seconds on the CLI I get the message that the Polycom is
unreachable. The phone still shows that it is registered and if I try
to place a call from the phone to my Cell, my cell rings once and then
stops. I get a packet retransmission error:
WARNING[1303]: chan_sip.c:4174 retrans_pkt: Retransmission timeout
reached on transmission [email protected] for seqno 2 (Critical
Response)
Followed by:
n_sip.c:4203 retrans_pkt: Hanging up call [email protected] - no
reply to our critical packet
I am "assuming" that there is a problem with NAT. I have externip set
in sip.conf.
Any pointers to what I am missing?
Thanks,
JohnM
